Pink River Dolphin. Pink dolphins live in rivers in South America: the Amazon, Orinocco, and upper Madeira. River dolphins are only distantly related to oceanic dolphins. They have learned to adapt to life in rivers and feed on crabs, catfish, small river fish, and small turtles.

Nomura's Jellyfish | Nomura’s Jellyfish | Giant Jellyfish

The Lions Mane Jellyfish -- largest jelly fish in the world. Found in the boreal waters of the Arctic. Some sea creatures just scare the crap out of me, and this would be one of them.

Lion's Mane Jelly fish The animal of the day is the Lion’s Mane Jellyfish. (Did you know: This is the largest species of jellyfish in the world! It’s bell [main body] can be up to 8 feet in diameter, and those trailing tentacles can measure up to 120 feet! [that's longer than a blue whale!] These species are only found in the cold waters of the Artic and North Pacific/Atantic oceans.

9.) Nomura’s jellyfish: This jellyfish is found off the coast of Japan and can weigh up to 440lbs. It’s about the same size as the lion’s mane jellyfish, the largest in the world. It’s easy to understand how Japan came up with Godzilla.

The Black Rain Frog (Breviceps fuscus) is a species of frog in the Brevicipitidae family. It is endemic to South Africa. Its natural habitats are temperate forests and Mediterranean-type shrubby vegetation. It is threatened by habitat loss #animal

The Black Rain Frog is a burrowing amphibian who is native to the Southern coast of Africa.

Most sharks and skates lay strangely shaped eggs sometimes called a ‘mermaid’s purse.’ These consist of an egg case in a thin capsule made of collagen. They often are square or rectangular with stringy or pointy corner horns, but can come in a variety of odd shapes. A few sharks, such as the Port Jackson shark, have helical egg cases which are secured into the sand like drill bits. Shark eggs can wash up on the beach and are often hand-sized, although the largest recorded was over 2m long.

Mermaid’s Purse - Catshark Egg Case Many species of catshark (family: Scyliorhinidae) lay eggs in tough egg cases known as mermaid’s purses. These cases have curly tendrils that tangle around objects to prevent them from floating away. The gestation period of the egg can range from a few months to over a year, depending on the species and water temperature. If held against a light source, the developing embryo can easily be seem.

About 40% of shark species lay eggs. The eggs are laid in a protective egg case (which is commonly called a "mermaid's purse"). It has tendrils that allow it to attach to corals, seaweed or ocean bottom. The young get nourishment from the yolk sac. | Photo by Sander van der Wel

Limacina helicina, the sea butterfly, is a tiny mollusk that lives inside a dark shell and uses its "ears" as wings. Like its predator, the sea angel, Limacina has evolved wings in place of the normal mollusk foot. Unlike the sea angel, though, Limacina hunts with a big ball of secreted mucous, which it uses to catch tiny arthropods, bacteria and algae. Photo by Alexander Semenov.

Beauty in Strangeness: Most Otherworldly Creatures on Earth (Wired article 2013-09-25) • not surreal mythology since we know more of the moon than our own oceans... glowing, ghostly, tiny & perfectly camouflaged creatures of the abyss • photos by marine biologist Alexander Semenov • just because they’re invisible let's not ignore them but enjoy their beauty, sustain them as much as us, before some go extinct due to global warming… • depicted: Limacina helicina (Sea Butterfly, White Sea, Russia)

Have you ever seen a sea butterfly aka the Limacina helicon? It is a lentil-size arctic snail that has a translucent shell and wings, which are evolved from its foot to keep it afloat as it drifts along the ocean and to trap plankton. #JungleJim #Animals #Snail #SeaButterfly #SeaAnimals #AnimalFacts #FunFacts

The narwhal, or narwhale, Monodon monoceros, is a medium-sized toothed whale that lives year-round in the Arctic. One of two living species of whale in the Monodontidae family, along with the beluga whale, the narwhal males are distinguished by a characteristic long, straight, helical tusk extending from their upper left jaw. Found primarily in Canadian Arctic and Greenlandic waters, rarely south of 65°N latitude, the narwhal is a uniquely specialized Arctic predator. In the winter, it feeds on benthic prey, mostly flatfish, at depths of up to 1500 m under dense pack ice. Narwhal have been harvested for over a thousand years by Inuit people in northern Canada and Greenland for meat and ivory, and a regulated subsistence hunt continues to this day. While populations appear stable, the narwhal has been deemed particularly vulnerable to climate change due to a narrow geographical range and specialized diet.

Narwhals Narwhals, swimming in the ocean, causing a commotion, cause they are so awesome, Narwhals Narwhals pretty big and pretty white, they could beat a polar bear in a fight, like an underwater unicorn, they've got an awesome facial horn, they're the jedi of the sea…..

Pterosaur Giraffe comparison

Giraffe-sized pterosaurs may have pole-vaulted with their arms to launch themselves, just as vampire bats do, scientists now suggest. Once airborne, these giant reptiles could have flown vast distances, even crossing continents, they added.
